Sean Owen commented on SPARK-3442:
----------------------------------
This exists in Guava as LimitInputStream until Guava 14, and as
ByteStreams.limit() from 14 onwards:
https://code.google.com/p/guava-libraries/source/browse/guava/src/com/google/common/io/LimitInputStream.java?spec=svn08d3526fc19293cf099e0c50dbf3bbc915f2e3f2&r=08d3526fc19293cf099e0c50dbf3bbc915f2e3f2
http://docs.guava-libraries.googlecode.com/git-history/v14.0/javadoc/com/google/common/io/ByteStreams.html#limit(java.io.InputStream,
long)
It would be nice to reuse but you can see the version problem there. At least,
maybe something that can be lifted and adapted.
